Purpose: To compare cancer screening rates via convenience community and random sampling from an academic medical center’s data warehouse (DW), compared with random digit dialing.
Methods: We compared demographics & screening rates from NYC BRFSS for Central Harlem (CH), East Harlem (EH) and the Upper East Side (UES), our catchment area, to data collected from random sampling from a medical center’s DW and community convenience sampling recruited from community & faith-based organizations, public housing, people on the street and attending neighborhood events. We oversampled from CH & EH to identify potential areas of need and focus for future research, outreach & intervention.
Results: We surveyed 1202 residents of our catchment area; 598 (50%) randomly chosen from the hospital’s 2018 DW and 604 (50%) from the community. See table below for racial distribution & rates of breast, colorectal (CRC) & lung cancer screening. Random sampling of DW reflected NYC racial distribution; community oversampling did not. Community convenience sampling did reflect NYC rates of screening for breast cancer and CRC; random sampling of medical center patients did reflect NYC rates for breast cancer screening, but did not reflect NYC rates for CRC. Lung cancer screening rates were significantly higher in the DW and Community than NYC.

Conclusions: For cancer screening, community sampling may be more representative of the challenges Community Outreach & Engagement programs face and can inform future directions for community based research, education, outreach and intervention.
